Hey guys,


I am currently rebuilding my 80 Series Land Cruiser. During the project, the original ECU was lost, so I'm trying to figure out if I have the right replacement unit and whether the plugs in my footwell are actually the engine ECU harness plugs.


Vehicle Specs:


Build Date: 02/1994 (Pre-facelift)


VIN: JT711UJ8008009616


Engine/Trans: 1FZ-FE (Manual Transmission, General Export / RHD)


Current State: 100% Petrol (the old aftermarket LPG conversion has been completely removed).


The Situation:


I picked up an 89661-60200 ECU (which has a 26-pin / 16-pin / 12-pin header setup). However, looking down in the passenger-side (left kick panel) footwell, I'm holding a few white/foam-wrapped connectors that don't seem to plug into this box.


Before I go any further, I want to confirm:


1. Are the wires/plugs shown in my photos the correct ECU connectors, or am I looking at body junction plugs and missing the actual engine loom plugs?


2. Is 89661-60200 the right ECU for a 02/94 manual 1FZ-FE, or do I need to buy an 89661-60320 (or another part number) for this build?


3. Do the 60200 and 60320 use different pinouts/plug configurations?


4. If these aren't the ECU plugs, where are the 3 factory engine loom connectors (26P/16P/12P) usually tucked or taped up when an ECU has been out of the vehicle for a while?


Photos attached:

Appreciate any advice, part number confirmation, or photos of the factory engine loom routing near the firewall grommet!


Thanks!

All of these look like body connectors.
Your ECU connectors will be above the glove box.

From the information you provided it seems like 89661-60200 is the correct part number for your ECU. in saying that 89661-60320 also comes back to the same chassis code. so Possibly a superseded part number.

Main engine harness connectors should be grey and up behind your glove box.
